TV remote controls use infrared (IR) radiation to send signals. The remote contains an LED light that flashes quickly to send messages, which the TV receives via its built-in infrared receiver. This is why infrared radiation is used for TV remotes.
Find the value of 'a' and 'b' which satisfy the following equations:
9a + 7b = 30
4a - 5b = 62
I. 2p2 + 5p + 2 = 0 II. 2q2 + 11 q + 14 = 0
The ratio of roots of an equation
ax²+bx+b = 0 is p : q
Then find, √p/√q + √q/√p + √p/√q ?
If x - √3 y = 8 Find the slope in angle?
I. p² - 365 = 364
II. q - √ 529 = √ 169
I. 8/(√x) + 6/(√x) = √x
II. y ³- (14)7/2 /(√y) = 0
For which value of m, there is no solution to the equation -
a – b = 5
ma – 4b = 1
Find the area between the lines 18x +12y = 108, 9x + 6y = 27, x - axis and y -axis.
If, x - y radic; 3 = 23 and radic; 3x + y = 35
Find the angle between both the lines when they intersect each other.
